2. BUILDING STRONG ® PORTLAND DISTRICT 2 BiOp Performance Standards for Dam Passage Survival RPA RM&E Actions - Strategy 2 (Hydrosystem RM&E): Monitor average Dam Passage Survival (S̅ Dam ) of juvenile run-of-river spring and summer migrants. Action Agencies operate to achieve and maintain performance standards of:  Spring: S̅ Dam ≥ 96% (SE ≤ 1.5%) across all dams for yearling Chinook and steelhead  Summer: S̅ Dam ≥ 93% (SE ≤ 1.5%) across all dams for subyearling fall Chinook salmon
